Hello everyone. I have taken the CS5O's introduction to programming with python offered by Havard university, which I consider a wonderful experience on my programming journey. The issue is, I have built my final project which requires a graphical user interface, so I used python's tkinter library and ttkbootstrap. But to my greatest surprise, when I copy-paste my final result, which I tested many times in my local editor (pyCharm), into their online editor for submission, I noticed that their online editor doesn't support windows creation (tkinter and ttkbootstrap). My concern is, can I still move on to submit it? Will they consider it a valid final project or I need to change project. Your pieces of advice are welcome!
